Former FBI Director James Comey discusses the meaning behind his "86 47" Instagram post with Stephen Colbert, following criticism and a Secret Service investigation.

Fox News producer Johnny Belisario confronted James Comey at a book signing to ask about his attention-grabbing anti-Trump Instagram post. But the former FBI director remained tight-lipped until Belisario was led away wanting more.

The Merriam-Webster dictionary traces “86” to “1930s soda-counter slang meaning that an item was sold out. There is varying anecdotal evidence about why the term eighty-six was used, but the most common theory is that it is rhyming slang for nix.”

Dan Bongino, the FBI's deputy director, condemned former FBI Director James Comey's "86 47" social media post as the FBI and Secret Service investigate potential threats.

Comey said he spoke with the Secret Service multiple times, including in person, about the post after agents contacted him.
